|Insert 'Sad that all the information I can find seems to be for the newer -U version of the chip, which does support 3.3V inputs (even when supply is 5V), as all signals above 2.2V are considered "high".  Might that work with the chip used on these boards as well?

[Of course the microcontroller needs 5V-tolerant I/ (mine does) or the return data will blow it up, I guess this can be prevented with either series resistors or by keeping the R/W line set correctly.]' at: '<!-- 39384.2488657407 EOR --><A style="color:#AF4040" TITLE="Click to login and reply" REL="nofollow" HREF="/techref/login/default.asp?req=/techref/update.asp%3Fact=reply%26url=/techref/io/lcd/new200907.txt%26id=39384.2488657407">+</A>'
